We are taking a summer break from December 21 to January. You can still place orders now and while we are on break. If we we receive but don't finish testing your samples before Christmas they will be at the top of our list when we re-open in January. Samples that arrive during the break will be stored carefully for testing in January.

Thanks for all the testing you've sent us this year, and have a wonderful summer!

DNA testing for health and appearance genes in dogs

Learn about one of the tests we do: B locus brown (bc allele)

Brown dogs can be found in many different breeds and cross-breeds. Brown dogs are often a beautiful chocolate colour, and have brown instead of black noses.

The brown coat colour in dogs is recessive. This means that some dogs that aren't brown still have the potential to produce brown puppies. It also means that when two brown dogs are bred together, they won't produce any black puppies.

This individual test is for the rarer brown variant, bc. Results are reported as either bc or n, where n could be B or another brown allele. To test for all three brown variants at once, try our B locus panel.
